摘要：
The microstructure and mechanical properties of deformed and subsequently aged Al-Cu-Mg alloy were investigated by employing transmission electron microscopy and hardness test. It was found that when the deformed alloy with 5%-strain was aged to peak temper, the strengthening mechanism was ascribed to the small dispersed S phases, which was different from the GPB zone as strengthening particle in conventional ageing. Besides, the main strengthening mechanism in the initial ageing stage was work hardening effect due to quantities of dislocation.
